Q1. A student's hand tremors during exams improve with beta-blockers. What physiological mechanism explains this?
Answer: Reduced sympathetic nervous system activity
Explanation: Beta-blockers inhibit fight-or-flight responses. Reduced sympathetic nervous system activity is correct because it matches what the question requires. USAT, HAT and MDCAT analytical sections repeat this pattern.
